Tips on How To Use Silicone Moulds
Sugarpaste & Modelling Paste
It is not necessary to treat the moulds with any grease or powder as they are non-stick (self-releasing). A flowerpaste, moulding or modelling paste should be used. If your paste is sticky it will not easily de-mould. This may be rectified by leaving the paste exposed to air to dry a little, then re-kneading and using it.
Placing the Silicone Moulds on a firm flat surface press chosen paste firmly into the mould. Using a rolling pin, roll from the center outward. With a thin spatula remove all excess paste. Using your fingers, push the paste from the edges toward the center to even the edges. Gently flex the sides of the mould to allow easy removal. Turn the mould over and flex until the paste falls out of the mould. For some of the small, shallow and delicate moulds, you may need to use a pin or tool to help release the paste out of the mould. For very detailed or deep moulds, refrigerate the filled mould or place it into the freezer for a couple of minutes (4 to 5 minutes) to firm up the paste, thus making it easier to de-mould.
Flowerpaste & Moulding Paste Recipe
Mix ingredients well and add desired colour. Knead thoroughly until paste is smooth and elastic. Wrap in a plastic bag and keep in an airtight container. Leave overnight to harden. Do not store in the fridge. Knead the paste every 2/3 days to prevent it from becoming too stiff.
Modelling Paste Recipe
10ml Egg White
30g White fat (Holsum/Wooden Spoon)
Mix pettinice/fondant and tylose. Knead thoroughly. Strain egg white through a sieve (to get rid of the chalaza)
and add to the paste. Soften fat and knead into paste until smooth and elastic. Wrap modelling paste in a plastic bag and store in a sealed container for 24 hours to mature. Do not store paste in the fridge as this will dry it out.
Use marzipan in the same way you would use sugarpaste or modelling paste. You should never use holsum or wooden spoon as this will make the marzipan too soft to mould. If it does become sticky, you can use maizena/cornstarch sparingly. You can place the filled Silicone Mould into the refrigerator or freezer to let the piece harden for easy de-moulding. Marzipan is best used for making pieces that do not have a lot of detail unless you change its texture by adding additional icing sugar to the mixture to stiffen it.
Store marzipan in a plastic bag in an airtight container in the refrigerator. If the marzipan becomes oily, press toweling paper on its surface to absorb the oil, and knead thoroughly again.
Silicone Molds that have a lot of detail or undercuts, are very shallow or very deep will not be suitable for chocolate moulding. Half fill your mould with chocolate, tap it a few times against the counter to get rid of trapped air and to get the chocolate into any detail, then fill the rest of the way and tap again. Continue to tap until all air bubbles have been released. Be sure not to over fill the mould. Scrape the excess off using a spatula.
Place the mould in the refrigerator or freezer until set.
Once set, carefully pop the piece out by gently flexing the sides of the mould to allow easy removal. Do not store finished chocolates in the refrigerator, store in an airtight container at room temperature.
Chocolate Modelling Paste Recipe
300g Dark Chocolate/White Chocolate
80ml Liquid Glucose
Melt the chocolate in a double boiler or in a microwave on very low heat and stir at regular intervals. Do not overheat as this may burn the chocolate. Add the liquid glucose, stir until it becomes thick. Cover and allow to stand for 3 to 4 hours or until firm. Add a bit of icing sugar and knead well, continue adding a little bit of icing sugar at a time until the consistency is smooth and it resembles a paste. This can now be used for modelling and moulding.
Make sure the cold porcelain mixture is totally smooth, then roll it into a ball, dust it with some cornstarch/maizena and press it into the mould. Using a rolling pin, roll from the center outward. With a thin spatula remove all excess paste, then smooth it again. Cold Porcelain is meant for thin moulds because it is air dry only, you do not bake it. It takes at least 24 hours to dry depending on the depth. Do not refrigerate to dry. Once dry, simply pop the piece out by gently putting pressure on the sides of the mould and flexing it out.
Cold porcelain can shrink when drying so do not use it for anything thick or very deep or it will crack. If the mixture is sticky you can either dust it with cornstarch/maizena, or you can place it in the microwave for 8 seconds at a time to remove some of the moisture.
Cold Porcelain Paste Recipe
250ml White Glue (Ponal in red bottle)
250ml Cornstarch/Maizena (sifted) & more for adding later
75ml Johnson’s Baby Oil
When heating, use indirect heat – a double boiler. If the pot is placed directly on the stove plate the paste will burn. In a pot, over medium heat, mix the glue and baby oil together and stir until smooth. Cook for a few minutes and add cornstarch/maizena. Mix very well and stir continually until the mixture thickens to form a paste. Remove from heat, cool slightly, then mix thoroughly with hands. Add more cornstarch/maizena if necessary, as much as it takes to form a good pliable paste. Wrap in a plastic bag and keep in an airtight container. Use as you would use any moulding or modelling paste. You can either dust the finished item with coloured chalks or powders or paint it with watercolour or acrylic paint.
Candles & Soap
If you we’re wondering How To Use Silicone Moulds with Candles & Soap, we have the answer! Candles & Soap making are specialized arts that require close attention to detail and safety precautions. There is so much information on the internet about candle and soap making that we suggest you do some research for yourself to determine whether or not you would like to learn these skills. Most of our moulds are too small to make candles and soaps and will thus be mainly used as an embed or inlay within a larger candle or soap.
Plaster of Paris
Mix the plaster of paris according to the manufacturer’s package directions. Break the surface bubbles with a spoon or spatula, then pour or spoon the plaster into the mould. Tap the mould on the counter to allow air bubbles to escape. You will need to work quickly before the plaster starts to set. It can take several hours or even days to set, depending on how thick or deep the mould is.
When the plaster is completely set, pop the piece out by gently holding the mould with your thumbs on top and fingers on the bottom of the mould and flexing it out.
If you are going to use a Silicone Mould that is deep or has undercuts you will need to pour the plaster in several stages while still working quickly. Pour a little plaster into the mould and move it around making sure you have it in all the detail before pouring in more. Paint the dry plaster item using any acrylic paint. First give the item a base coat (white or off white is fine) and allow it to dry, before giving it a final coat. The finish will be much smoother and it will be easier to paint with colour.
There are so many different types of clay available on the market today. Please follow the manufacturer’s instructions of the particular clay that you will be using. It is advisable to knead the clay well until it has a soft and smooth finish and does not crack or break off into small pieces. To check if you are done conditioning, you should roll the clay into a snake shape about the size of your thumb. If the clay cracks when you bend the snake in half you should continue working with it to get it softer and more pliable.
Roll the clay into a ball and dust it with cornstarch/maizena before pushing it into the mould. Using a rolling pin, roll from the center outward. With a thin spatula remove all excess clay, then smooth it again. Using your fingers, push the clay from the edges toward the center to even the edges. Gently flex the sides of the mould to allow easy removal. Turn the mould over and flex until the clay falls out of the mold. For some of the small, shallow and delicate moulds, you may need to use a pin or tool to help release the clay out of the mould. For very detailed or deep moulds, refrigerate the filled mould or place it into the freezer for a couple of minutes (4 to 5 minutes) to firm up the clay, thus making it easier to de-mould.
Let the finished piece come to room temperature on waxed paper before baking. You must bake polymer clay. Follow the manufacturer’s package instructions, or it will remain soft, it does not air dry.
If your clay is too firm even after conditioning you can add a tiny amount of petroleum jelly (Vaseline) to it.
If the clay becomes too soft you can let it rest overnight or place it in the refrigerator for an hour or so to firm it up. Once your moulded item is completely baked and dry, you can now paint it by using any acrylic paints.

How to use silicone moulds
Shirley Treichel had for many years tried many different hobbies when she discovered that she enjoyed working with chocolate. She made and sold a large variety of chocolates as a hobby, which she enjoyed very much. She attended a day of demonstrations where she saw a demo on how to make one’s own silicone moulds. She was eager to try to make her own chocolate moulds, so she bought some moulding material and made some for her personal use. At the branch of the SACDG where she belonged, they had a competition at the end of the year where they made plaques with icing decorations on them. Being new to this craft, Shirley did not have the skills or knowledge yet to produce a work of art, so she took the easy way out and used the silicone moulds she made for herself. Members of the branch asked where she got the silicone moulds to make the icing decorations. After two or three years of being asked the same question, where can they buy Silicone Moulds in the Pretoria area, she realised there was enough of a demand for Silicone Moulds for cake decorators. There were some Silicone Moulds available from other manufacturers, but not a large variety and she had a totally different range of silicone moulds that she had made for her own use. Shirley realized that there was a market gap and decided that she would make them for resale. The rest is history! Shirley’s Silicone Molds is now one of the leading silicone mould suppliers in South Africa. I decided to try this newfound interest and art form and thus joined the South African Cake Decorators Guild in the year 2000. I finally found the hobby that most intrigued me. And That’s When My Hobby Started… We now have the best quality silicone that we use to manufacture all of our Silicone Moulds. Shirley's Silicone Molds now has a large client base all over South Africa and also supply silicone moulds to some retail outlets. Being a Silicone Moulds Suppliers, we have been manufactured to make the most of our quality materials and our experience, with flexibility, innovations, personalization and client support is what makes us succeed. We take great pride in every silicone mould that we manufacture and our motto is always to try for perfection. Our range of Silicone Moulds is always extending and we try to keep up with the trends and demands of today and thus manufacture new moulds on a continuous basis. We see in each accomplishment a New Beginning!
